Overview

DID YOU KNOW 

SAFE DRIVING STARTS AND ENDS 

WITH CLICKING AND COMPREHENDING. 

When it comes to driving, it’s the little things that often make the biggest 

difference. Like fastening your seatbelt before you take to the highway. 

According to the U.S. National Highway Traffic Safety Administration, 

seat belts reduce serious crash-related injuries and deaths by roughly 

50%. That’s a huge number for such a simple action. 

Another smart but simple thing safe drivers practice is reading 

comprehension. Not just reading every single highway sign, but 

understanding and acting on them all. Obeying signs saves time 

and speeding tickets. It also alerts you to dangers that can easily 

cost you your life. 

At Halliburton, solving customer challenges is second only to 

keeping everyone safe and healthy. You can find more safety tips

Driving Safety 

The Halliburton 10 to Zero Life Rules are a compilation of basic rules 

that all Halliburton employees know and live by. These are key 

components for identifying and managing the hazards in our business.

Challenges Addressed 

• Improve net recovery from 

new and old fields by 

allowing the completion of 

layered zones and stringers 

previously bypassed

improving the economics of 

ultra-deepwater and deep 

reservoirs
